The CP+ show in Yokohama, Japan is just around the corner, and many manufacturers are using the opportunity to announce new products or give status updates on current developments. The former is true for Cosina, who has just announced an updated version of its Voigtländer Nokton 25mm f/0.95 lens for Micro Four Thirds, and the latter is true for Sony, who has just announced a price tag for its upcoming 70-200mm f/4 full-frame E-mount lens.

The Cosina Voigtländer Nokton 25mm f/0.95 was the fastest production Micro Four Thirds lens when it was originally announced, and has been complemented with a 17.5mm f/0.95 and a 42.5mm f/0.95 sibling in the meantime. The 17.5mm Nokton was the first of the series to sport an aperture ring that could be switched to operate clicklessly, and now Cosina decided it's time to introduce the same feature to the 25mm as well.

Optically, the 25mm f/0.95 Nokton will stay the same, but the barrell now looks slightly different due to the added mechanism in the aperture ring. The weight of the new lens is slightly up by 25 g (0.8 oz) and the price will also be slightly higher than that of the original version – DC Watch quotes JPY110,250, which translates to US$1,075 at current exchange rates. However, the clickless aperture ring will probably be highly appreciated by videographers.

Meanwhile, Sony has announced a price tag for its upcoming 70-200mm f/4 FE-mount lens, which will be compatible with both full frame and APS-C sensors. For about US$1500, users of an Alpha 7 or 7R will soon get a proper telephoto zoom lens that covers the common focal length range of 70-200mm. Users of an E-mount camera with APS-C sensor will get to use the lens at equivalent focal lengths of 105-300mm.

Both the Nokton 25mm f/0.95 and the Sony FE 70-200mm f/4 will be available in March.
